Summary
python2.7, python3.5 vulnerability
Details

USN-7015-1 fixed several vulnerabilities in Python. This update provides the corresponding update for CVE-2023-27043 for python2.7 and python3.5 in Ubuntu 14.04 LTS.

Original advisory details:

It was discovered that the Python email module incorrectly parsed email addresses that contain special characters. A remote attacker could possibly use this issue to bypass certain protection mechanisms. (CVE-2023-27043)

It was discovered that Python allowed excessive backtracking while parsing certain tarfile headers. A remote attacker could possibly use this issue to cause Python to consume resources, leading to a denial of service. (CVE-2024-6232)

It was discovered that the Python email module incorrectly quoted newlines for email headers. A remote attacker could possibly use this issue to perform header injection. (CVE-2024-6923)

It was discovered that the Python http.cookies module incorrectly handled parsing cookies that contained backslashes for quoted characters. A remote attacker could possibly use this issue to cause Python to consume resources, leading to a denial of service. (CVE-2024-7592)

It was discovered that the Python zipfile module incorrectly handled certain malformed zip files. A remote attacker could possibly use this issue to cause Python to stop responding, resulting in a denial of service. (CVE-2024-8088)
